What is the relationship between linear and angular speed in golf?
Linear and Angular Speed in the Golf Swing. Now linear and angular velocity are related by v = r x w where v is linear velocity (in ft/sec, mph or m/s) and r is the radius of the circle (in feet or meters) and w is the angular velocity (in radian/second or degrees/second). What this equation means is that for a given angular velocity,...
What is the physics of a golf swing?
The Physics Of A Golf Swing. Part of the physics of a golf swing (from the point of view of the golfer), means finding the release (wrist uncocking) point so that at the bottom position, where the players hands are directly above the ball, the golf club is in the vertical position parallel to his arms.
What is the shortest distance between two points in a golf swing?
When describing the shortest distance between two points, a straight line is the shortest. But in the case of the golf swing, the widest distance of the arc is also where the low point of the arc is. This happens to occur where the left arm/forearm lines up straight with the shaft.
How do you calculate the angular velocity of a golf club?
Of course the club has this type of motion during the swing (especially the downswing). Now linear and angular velocity are related by v = r x w where v is linear velocity (in ft/sec, mph or m/s) and r is the radius of the circle (in feet or meters) and w is the angular velocity (in radian/second or degrees/second).
What is velocity vector?
Velocity (a vector) involves a ‘change in position’ aka ‘displacement’ over a
Is acceleration positive or negative?
Acceleration can be positive, negative or zero based on direction of motion AND direction of change of velocity (slowing down/speeding up/constant)
How to maximize your golf swing speed?
To maximize your velocity in the golf swing, you have to get your upper body and lower body to work together, which is easier said than done. You might be able to generate power with the shoulders and arms to rotate your upper body. You might be able to generate power with the legs and hips to rotate your lower body.
What is the rate of speed in a specific direction?
Velocity is the rate of speed in a specific direction. For golfers, velocity is measured in club head speed at impact. Increase your velocity and you increase your club head speed. Increase your club head speed and you increase your power and distance.
Why does my lower back rebel against me?
Off the course, all of that repeated explosive and rotational movement around the spine will eventually cause your lower back to rebel against you. We just weren't built as species to rotate that dynamically around the spine.
Can you rotate your lower body with your legs?
You might be able to generate power with the legs and hips to rotate your lower body. But syncing them together with precise timing to generate maximum velocity is a whole different animal. One of the major issues preventing golfers from properly syncing the upper body with the lower body is that each is moving at a different speed.
Which body part moves the fastest in golf?
The legs, which are closer to the "eye" or center of your golf swing rotate slower, though no less powerfully, than the arms and upper body, which are farther away from the center of the swing. The club head, which is the farthest from the "eye of the swing," moves the fastest.
When driving on the highway, do you always respect the speed limit?
Remember: when you're driving on the highway, always respect the speed limit; when you're driving onto the fairway, there are no speed limits. Up your velocity!
Can you swing a golf club with your arms?
You can swing a golf club using just your arms. It doesn't weigh a whole lot, so you can get away with a really arms-y swing if you want to. I'm sure you've seen, or played with, many folks that play this way. There are a couple of problems with this, though.
What is the path of a golf ball when hit down?
When you hit down on a golf ball, your path is shifted to the right (for a right-handed golfer), and when you hit up on a golf ball your path is shifted more left. With the longer clubs, this is a 1:1 ratio, but with the shorter clubs is not quite that much. So by examining the data above, you can see that indeed the swing direction was out-to-in, but this player hit down on the ball -5.7 degrees and this shifted his actual path to 1.3 degrees from the inside (shown by the blue line). Thus, this player was hitting very slight push draws with leftward pointing divots when his face angle was left of his path.
What happens when you hit a shot off line?
Whenever someone hits a shot off-line, they tend to step back and audit the direction of their divot and base their “fix” on moving their swing path and subsequent divot in a more target-ward direction . This sadly, is incorrect in two ways:
What is the swing path of a golf club?
Your swing path is defined as how far left or right of the target line the club head is traveling through impact. Look at the photo above, and you will see that the swing direction is -2.7 degrees, however you must take into account your swing’s angle of attack in order to understand true path of the club head at impact.
What is the swing direction of a golf ball?
So what does this all mean? The swing’s direction is simply how far left or right of the target line the “direction of the swing” is aimed at the bottom of the swing arc. So, if you look at the photo above you will see that the swing direction of this player is -2.7 degrees, or a couple degrees from out-to-in relative to his intended target line, which is shown by the thin white line running through the ball.
What does dropping the mic on wrists do?
Drop the mic on how the wrists should load and be positioned for compressive power, accuracy, and longevity! There is a better way, and this is it!
Do divots tell you the swing path?
I know it is tough to comprehend that divots do not tell you much about swing path, angle of attack, the lie angle of the clubs, starting direction, or even ball curvature, but it’s been proven over and over with the Trackman and its D-Plane data. (See www.leitzgolf.com for several great videos on understanding more about the D-Plane.)
Can you move your swing direction?
NOTE: You can always move your swing’s direction by altering your aim at address, ala Fred Couples, however, for the sake of this article we are going to assume you are always going to line up square to your ball’s target line.
What did David Leadbetter teach?
Then in the late 80’s David Leadbetter comes along to argue against the excessive lateral shifting and emphasized trunk rotation as the way to hit the ball. “Use the big muscles” and “rotate the chest” were things taught to me along with the early wrist set and re-hinge on the follow through. He used vague term of “turning weight shift” which meant that the better players shifted slowly while rotating. These ideas certainly helped players like Nick Faldo, Nick Price, Dennis Watson, Ernie Els and others to achieve great things. But now, 25 years later, he’s teaching stay closed with body, swing the arms down and slide laterally.
What is the worst shot golfers suffer from?
Second, they believe that the worst shot golfers suffer from is a slice with the villain being rotation as the main cause of swinging over the top which then makes the downswing steep and the path to be directed too far left or out to in. So they recommend sliding laterally which will cause a secondary axis tilt. By getting the secondary axis tilt, this will cause a drop of the shoulders, tilt the spine away from target and then the club has to come from the inside. The right arm extension or “throwaway” this will enable the slicer flatten his/her plane thus enabling a more in to out path but it does so at the expense of holding lag.
How does one hit a driver well with that idea?
Also how does one hit a driver well with that idea? Well you slide left then create a “secondary axis tilt” that is comprised of a lateral slide, right pelvic tilt and having the upper body shift backwards away from the target.
What is the endless slide?
It’s called the endless slide. If you slide enough, you can get your low point in front of the ball despite having an overly flat swing and an early casting of the wrists. So you see, this is how sliding is imperative and is the Savior. How else are you going to get 85-90% weight on left side at impact as they promote?
What is the power of rotation in baseball?
A home run hitter in baseball rotates immediately after the step therefore the powerful rotation is used to create bat speed. There is no one at the MLB home run derby with a lateral slide and restriction of rotation. The chest and belt buckle are practically pointed at the pitcher at impact. Huge rotation.
What happens if your right arm extends?
But this action causes several more problems as well. If the right arm extends, it will trigger early wrist ulnar deviation as well or what we call “casting.” Advocates would say it will flatten and shallow out the plane. I agree but isn’t there a point where it can cause too much flattening/shallowing? Won’t that cause the low point or bottom of the swing arc to become too far behind the ball (causing fat shots)? Add to the mix that most amateurs will flip, that will cause even more problems with low point getting way behind the ball.
Why do the best long drive competitors continue to rotate rather than slide?
If that is all true, then why do the best long drive competitors continue to rotate rather than slide? Is it because they only listen if helps them hit it longer? In a sport where only the longest wins, the long drive competitors are truth detectors and can see through the marketing . If deceleration of their limbs made them hit it farther, you can bet they’d all be doing it. But if the idea doesn’t pan out in competition, forget it. They can’t afford to listen.
